FLAT HOSIERY MACHINE Filed 061.. 6, 1955 United States Patent G FLAT HOSIERY MACHINE Anton Loimann, Unterrot-Arwatal, Germany, assignor to Arwa-Feinstrumpfwirkerei G. in. b. H., Backnang (Wurtt), Germany Application October 6, 1955, Serial No. 538,957

1 Claim. (Cl. 66-110) The invention relates to a flat hosiery machine having dividing sinkers and jack sinkers of improved construction. By improving the construction of the jack sinkers and dividing sinkers it is intended to prevent the butts of the dividing sinkers from striking up against the butts of the jack sinkers when the sunk loops are being divided.

With the increasing operating speed and delicacy of flat hosiery machines, it has been found necessary to protect the butts of the dividing sinkers from striking up against the butts of the jack sinkers when the sunk loops are being divided. Even slight vibration of the catch bar at high speeds can result in the butts of the dividing sinkers striking against the butts of the jack sinkers. The object of the present invention is to obviate this disadvantage.

According to the invention the butts of the dividing sinkers are provided with guide means which keep the butts of the dividing sinkers and the butts of the jack sinkers guided on one another in every position, and especially after the loops, have been sunk. The per se known thickening pieces (fittings) on the butts of the jack sinkers or on the dividing sinkers have proved to be suitable guiding means, the appropriately shaped thickening pieces keeping the sinkers guided on the butts of the nonreinforced sinkers and vice versa, in every position of the sinkers. This can be achieved by making the butts of the fittings relatively large or providing them with a projection, so that the butts or projections remain in contact in every position of the sinkers and guide one another.

Another constructional form suitable for preventing the sinkers from striking against one another consists in that the dividing sinkers are prevented from deviating laterally by a notched ledge which is arranged in the catch bar and in whose notches the sinkers are held.

Several constructional-examples of the invention are illustrated in the drawings.

In the example according to Fig. 1, the butt 3 of the jack sinker 1 and the butt 4 of the dividing sinker 2 are of such a width that even after the loops have been sunk, the butt of the dividing sinker 2 remains in the region of the butt of the jack sinker and it is not possible for the edges of'the butts to strike up against one another.

According to the example in Fig. 2 the same effect is achieved as in the preceding example by providing the butt 3 of the jack sinker, which is of normal width, with a projection 5 which remains in contact with the butt 4 in every position of the two sinkers 1 and 2.

Alternatively, as the example according to Fig. 3 shows, the butt 4 of the dividing sinker 2 can be provided with a projection 6 which likewise maintains contact with the butts of the two adjacent sinkers irrespective of the position of the sinkers.

What I claim and desire to secure by Letters Patent is:

In a flat hosiery machine, a plurality of dividing sinkers and jack sinkers, each said dividing sinkerbeing formed with a butt portion, each said jack sinker being formed with a butt portion, said butts of all said sinkers being further formed in such shape and size that the butts of the dividing sinkers and the butts of the jack sinkers are in continuous lateral sliding contact with one another in every position of said sinkers and serve as guide means therefor. 7
